Ištisinio liejimo plokščių segregacijos vidurinėje zonoje įvertinimas (ISO 21224:2025)

This document specifies a procedure for the evaluation of centreline segregation of continuously cast slabs, including sampling, sample preparation and evaluation method. This document is applicable for low carbon steel slabs for pipe production manufactured by continuous casting. These steels have a typical chemical composition as follows (mass percentages): — C ≤ 0,12 % — Mn ≤ 2,0 % — Si ≤ 0,5 % — Ti + Nb + V ≤ 0,2 % The common dimensions of these slabs are in the following ranges: — Slab width: 800 mm to 2 600 mm — Slab thickness: 150 mm to 450 mm The evaluation methods covered by this document are based on macroscopic etching of slab samples followed by visual inspection by means of human eye or camera systems. The procedures for sampling described in 5.1 to 5.3 of this document are applicable to steels slabs in general (e. g. other steel grades or dimensions). However, the etching procedure (see 5.4) in combination with the evaluation methods described in Clause 6 have been developed especially for the application on pipeline steels as given above. Thus, they are not applicable to other steel grades, product types or dimensions without a prior validation. Any extension or modification beyond the scope of this document necessitates a separate agreement between producer and customer.

Intelektinės transporto sistemos. Judumo integravimas. Transporto priemonių eismo apribojimų mieste taikymui skirtas kontroliuojamųjų zonų valdymas naudojant sąveikiąsias ITS (ISO 24311:2024)

This document provides information and specifications on the management of road traffic in controlled zones (CZ) through the application of geofencing. Specifically, this document specifies a “Controlled Zone Data Dictionary” (CZDD) for management of controlled zones, and provides an extendible toolkit that regulators can use, for example, to inform potential CZ users (e.g. vehicles) about: — the CZ area, i.e. the geographical boundaries of the CZ; — CZ access conditions including exemptions; — time windows indicating when these CZ access conditions are applicable. This allows potential CZ users to select an appropriate routing, either by pre-trip planning or ad hoc re-routing. This document also provides illustrations and guidelines on how to use this toolkit. The toolkit is designed in accordance with the general ITS station and communications architecture specified in ISO 21217, and with optionally applicable C-ITS protocols and procedures, e.g. ISO 22418 on “Service Announcement”, ISO 18750 on the “Local Dynamic Map”, and ISO 17419 on globally unique identifiers. Cybersecurity provision can be provided through conformance to ISO 21177. Enforcement is out of scope of this document.

Stacionariosios gaisro gesinimo sistemos. Automatinės sprinklerinės sistemos. 1 dalis. Projektavimas, įrengimas ir techninė priežiūra

This European Standard specifies requirements and gives recommendations for the design, installation and maintenance of fixed fire sprinkler systems in buildings and industrial plants, and particular requirements for sprinkler systems that are integral to measures for the protection of life. This European Standard covers only the types of sprinkler specified in EN 12259 1 (see Annex L). The requirements and recommendations of this European Standard are also applicable to any addition, extension, repair or other modification to a sprinkler system. They are not applicable to water spray or deluge systems. It covers the classification of hazards, provision of water supplies, components to be used, installation and testing of the system, maintenance, and the extension of existing systems, and identifies construction details of buildings which are the minimum necessary for satisfactory performance of sprinkler systems complying with this European Standard. This European Standard does not cover water supplies to systems other than sprinklers. Its requirements can be used as guidance for other fixed firefighting extinguishing systems, provided that any specific requirements for other firefighting extinguishing supplies are taken into account. This European Standard is intended for use by those concerned with purchasing, designing, installing, testing, inspecting, approving, operating and maintaining automatic sprinkler systems, in order that such equipment will function as intended throughout its life. This European Standard is intended only for fixed fire sprinkler systems in buildings and other premises on land. Although the general principles might well apply to other uses (e.g. maritime use). For these other uses additional considerations should be taken into account. The requirements are not valid for automatic sprinkler systems on ships, in aircraft, on vehicles and mobile fire appliances or for below ground systems in the mining industry. Sprinkler system design deviations might be allowed when such deviations have been shown to provide a level of protection at least equivalent to this European Standard, for example by means of full-scale fire testing where appropriate, and where the design criteria have been fully documented.
